ENGLISH BOTANY. 



ORDER LUI.— LABIATJE. 



Herbs, iinderehrubs, or, more rarely, shrubs with the stem, or at 

 least the branehes, 4-siclccl. Leaves always 0[)i)Ositc, generally i'ragraiit, 

 from containing essential oil; without stipules. Flowers perfect, ir- 

 regular, generally in small subscssile cymes in the axils of the upper 

 leaves or bracts ; the flowers of these cj-mes apparently meeting round 

 the stem and forming false whorls or verticillasters ; sometimes forming 

 a raceme or spike-like raceme ; rarely only a single flower is produced 

 in the axils of each bract or leaf, so that they are in pairs at each 

 node. Calyx 5-toothed ; the teeth sometimes so combined that it 

 becomes bilabiate, and sometimes even with apparently only 2 teeth 

 or lobes. Corolla hypog}'nous, tubular, with an irregulai' limb, usually 

 bilabiate and ringent. Stamens 4, didjTiamous, more rarely 2, inserted 

 in the tube of the corolla. Ovary of 2 carpels, each so deeply divided 

 that the ovaiy is d-celled and 4-lobcd, with a single style coming from 

 the centre of the 4 lobes, and consequently apparently from the base 

 of the carpels ; stigma more or less 2-lobed ; ovules 4, 1 in each cell or 

 lobe of the ovary. Fruit of 4 separate indehiscent cocca usually called 

 nucules, each enclosing a single erect seed. Embryo almost always 

 straight; albumen none, or in very small quantity and fleshy. 



Tribe I.— MENTHOIDE/E. 



Corolla funnel-shaped, scarcely bilabiate. Stamens 4, rarely 2, 

 divergent, nearly equal ; anthers 2-cclled, cells contiguous. 



GENUS 7.— LYCOPUS. Linn. 



Calyx regular, 5-toothed, teeth flat. Corolla funnel-shaped, nearly 

 reguhu-, 4-lobed ; upper lobe generally notched. Fertile stamens 2 ; 

 the upper or inner pair sterile, or absent ; anther-cells parallel, or 

 ultimately divergent. Nucules truncate at the apex, surrounded by 

 a corky border at the base.
